Assume that the following equations characterize a large open economy: (1) Y = 5,000 (2) Y = C+1+G+NX (3) C=1/2(Y-1) (4) 1 = 2,000-100r (5) NX = 500 - 500 E (6) CF=-100r (7) CF = NX (8) G= 1,500 (9) T= 1,000 where NX is net exports, CF is net capital outflow, and & is the real exchange rate. Solve these equations for the equilibrium values of C is S , I is S , NX is , CF is S , r is %, and & is (Hint: You can reduce the total number of equations to two through repeated substitutions. These two equations will be functions of r and s. Check your work by seeing that all of these equations balance, given your answers.)
